When you want maximum pump and performance—without stimulants—this is where you go.
Gene Blast Stim-Free Pump Pre-Workout is built around one goal: deliver intense muscle fullness, consistent output, and clean training sessions without relying on caffeine. Each full serving provides 8g of pure L-Citrulline, giving you clearly defined dosing to support nitric oxide production and pump-focused training—no diluted blends, no guesswork.
The formula is reinforced with a nitrate and volumisation complex combining natural nitrates and glycerol to help drive muscle fullness, endurance, and sustained session intensity. Whether you’re chasing that tight, full pump or pushing through longer hypertrophy sessions, this system is designed to keep output consistent from start to finish.
To support performance under pressure, the hydration and output matrix delivers 2g Betaine and 2g Taurine alongside essential electrolytes including sodium, potassium, and magnesium—helping maintain fluid balance, muscle function, and training consistency when it matters most.
This is a fully stim-free system, giving you total control over your intake. Train late without compromise, avoid overstimulation, or stack it alongside stimulant-based formulas as part of a structured routine.
No proprietary blends. No hidden dosing. Just a transparent, performance-driven formula manufactured in GMP-compliant facilities and suitable for vegan and halal lifestyles.
Built for athletes who want to train harder, longer, and more efficiently—without relying on stimulants.
